JACKSON J. KENNEDY, OF CLEVELAND, TENNESSEE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 356,320, dated January18, 1887.

Application filed November 30, 1886. Serial No. 220,308.

.To all whom, it may concern:

Be it known that I, JACKSON J. KENNEDY, of Cleveland, in the county ofBradley and State of Tennessee, have invented a new and usefulImprovement in Car Couplings, of which the following is a specification.

Figure 1 is a plan view of the coupling. Fig. 2 is a verticalcross-section through the line a: 00, looking in the direction of thearrow. Fig. 3 is a section of the draw-bar where it passes through thebearings in the frame-work of the car. Fig. 4c is a cross-sectionthrough line y y of Figs. 1 and 5, and Fig. 5 is a longitudinal sectionof the draw-bar through its slot.

My invention relates to certain improvements upon the form ofcarcoupling patented by me August 8, 1882, No. 262,433, and May 25,1886, No. 342,608; and it consists, mainly,

in the improved construction of the drawbar, its locking-key, and itsbearings, as will be hereinafter fully described, and pointed out in theclaims. I

In the drawings, A. represents the draw-bar, which, as described in myprevious patents, is a rotary adjustable draw-bar, oscillating about thelongitudinal axis, and having at its front end an offsetting goose-neck,a, head b, and inclined beak c, whichlatter occupies a diagonal positionbetween the verticaland horizontal, and is'bevelcd on its face, so thatwhen the two beaks of the opposite draw-bars come together the inclinedfaces of the beaks cause the draw-bars to turn axially until the beakspass, and they'then are-rotated by their own gravity back again into thenormal diagonal position and hook or lock into each other, so as tocouple the cars, as in Figs. 1 and 2.

One feature of improvement consists in making the head I) of eachdraw-bar large and forming it with a link-throat, d, with closed sides,and a pin-hole and pin, 6, which adapt it to couple with the draw-barsof ordinary cars, the offset in the goose-neck permitting the draw-headto be adjusted either abovethe central line or below the central line bybeing turned over, and thus adapting this head to couple with cars ofdifferent heights.

\Vhere the draw-bar passes through the ,draw-bar and formingoil-cavities.

(No model.)

bearing in the frame-work D of the car, said U bearing is recessed, sothat only certain points of the inner face of the bearing touch thedraw-bar, as shown at f f f f, Fig. 3, the intervening spaces being outof contact Wit-h the This reduces friction and renders the rotary actionof the draw-bar easier and free from cramping strains.

To render the draw bar yielding, its rear end is reduced in diameter anda shoulder left at 1", against which a ring or disk, at, bears, andbehind which a spiral spring, D, is disposed and wound around the shalt.The rear end of this spring bears against a ring or disk, C, and this inturn bears against a shoulderkey, B. passing through a slot inthedrawbar. This arrangement, in connection with cross-bars E E, makesthe draw-bar elastic both in pulling and backing. To hold the key B inplace, it is formed on'one side with a shoulder, s, Fig. 4, whichprevents it from passing through the slot, and on its edge it has ashoulder, t, Fig. 5, which is overlapped by the ring C, and by it isprevented from 00111- ing out. To reinovekey B, ring-C is pressed backagainst the spring D till shouldertis cleared, and the key can be thenwithdrawn.

Having thus described my invention, what I claim as new is 1. Thecombination, with the slotted drawbar, the spiral spring D, and ring C,of the shoulder-key B, having a shoulder, s, on its side and anothershoulder, t, on its edge, arranged to be overlapped and locked by thesaid ring, substantially as described.

2. An axially-oscillating draw-bar having a goose-neck, a, head b, andbeak c, offsetting from the axial line, with a linkthroat, d, and pinhole formed in the head, substantially as and for the purpose described.

3. The combination, with an axially-oscillating drawbar, of a bearingfor the same, having a recessed inner periphery to reduce friction,substantially as shown and described.
